Japan Launches 8K Resolution Broadcasts Ahead of Rio Olympics

The 2016 Rio Olympics are days away (the Opening Ceremony kicks off on August 5), but Japan is already planning for the 2020 Olympics in Tokyo. According to Engadget, Japanese broadcaster NHK recently began Super Hi-Vision broadcast tests, which allow for live feeds to be sent via satellite in 4K and 8K resolutions with 22.2 channel sound. With the Rio Olympics as a trial run, the plan is to have everything running smoothly by 2018 for the Olympic Games.

Because most citizens don't have 8K televisions yet, NHK will host tests at public locations in Tokyo and Osaka during the Rio Games. The group will broadcast a live stream of the Opening Ceremony and other pre-taped 8K footage shot at the London 2012 Olympics.

Seeing is believing, when it comes to 8K resolution. It's hard to accurately picture what the feature looks like without the right equipment, but you can check out CNET's breakdown of the differences between existing resolutions.

In 2017, a juggler named Alex Barron broke a record when he tossed 14 balls into the air and caught them each once. The feat is fascinating to watch, and it becomes even more impressive once you understand the physics behind it.

As WIRED explains in a new video, juggling any more than 14 balls at once may be physically impossible. Researchers who study the limits of juggling have found that the success of a performance relies on a number of different components. Speed, a.k.a. the juggler's capacity to move their hands in time to catch each ball as it lands, is a big one, but it's not the most important factor.

What really determines how many balls one person can juggle is their accuracy. An accurate juggler knows how to keep their balls from colliding in midair and make them land within arm's reach. If they can't pull that off, their act falls apart in seconds.

Breaking a juggling world record isn't the same as breaking a record for sprinting or shot put. With each new ball that's added to the routine, jugglers need to toss higher and move their hands faster, which means their throws need to be significantly more accurate than what's needed with just one ball fewer. And skill and hours of practice aren't always enough; according to expert jugglers, the current world records were likely made possible by a decent amount of luck.

The great Yogi Berra—a 10-time World Series champion and three-time MVP—was one of baseball's best catchers, but he's remembered just as much for his wit and wisdom as his Hall of Fame career. Here are some of the quotes attributed to Yogi (who was born on May 12, 1925), even if he didn't alwayssay them first.

1. "Always go to other people's funerals, otherwise they won't go to yours."

2. "The future ain't what it used to be." (Yogi later clarified, saying, "I just meant that times are different. Not necessarily better or worse, just different.")
